uefi problem? can't boot with ssd when data disk is connected

http://forums.fedoraforum.org –
let me start off by saying althought I am not an expert, I am an experienced noob. I recently got a new system with gigabyte z77x ud5h mobo along with an SSD and a data disk. I cannot begin to tell you how many time I have tried to install but each time fedora fails to boot. I even got RHEL6 disk and tried (thinking it was usb install issue), same story. Here was my partition layout.
In the SSD
/boot 1 GB
/root 111 GB
/swap 10 GB
In Data Disk
/home ~2TB.
The installation would go fine but I get stuck on Grub (newline) Welcome to Grub! occasionally it would dump me to grub rescue prom

My BIOS has some problems and sometimes boot order of disks changes. I thought that if I insall grub on to the MBR of second data disk, it may boot. First disk(sda) is for boot and operating system, second disk(sdb) is for /var. All partitions are labeled and fsck has labels as partition references.

I have install grub on to MBR of second disk by "grub-install /dev/sdb".
